-Knative Lambda Runtimes (e.g KLR, pronounced _clear_) are Knative [build templates](https://github.com/knative/build-templates) that can be used to run an AWS Lambda function in a Kubernetes cluster installed with Knative.
+Knative Lambda Runtimes (e.g KLR, pronounced _clear_) are Tekton [Tasks](https://github.com/tektoncd/pipeline/blob/master/docs/tasks.md) that can be used to run an AWS Lambda function in a Kubernetes cluster installed with Knative.
 
 The execution environment where the AWS Lambda function runs is a clone of the AWS Lambda cloud environment thanks to a custom [AWS runtime interface](https://github.com/triggermesh/aws-custom-runtime) and some inspiration from the [LambCI](https://github.com/lambci/docker-lambda) project.
 
 With these templates, you can run your AWS Lambda functions **as is** in a Knative powered Kubernetes cluster.
 
-The examples below use the [tm](https://github.com/triggermesh/tm/releases/latest) CLI to interact with Knative but one could also use `kubectl`:
